虚工作在双代号网络图中的主要作用是处理各工作之间的彼此关系,它的正确使用是绘制双代号网络图的关键。本文就建筑工程施工组织设计中工作的概念和分类、网络计划的逻辑关系和虚工作的表示方法、虚工作在双代号网络图中的作用以及在绘制双代号网络图中如何正确使用虚工作进行了阐述,通过案例分析与解答,进一步说明正确使用虚工作在双代号网络图绘制中的重要性。
The main role of virtual work in the double code network diagram is to deal with the relationship between the various work, and its correct use is the key to drawing a double code network diagram. In this paper, the concept and classification of construction work in the construction design, the logical relationship between network planning and virtual work representation, the virtual work in the dual-code network diagram and how to draw the double-code network diagram in the correct use of virtual work Elaborated, and through case studies and answers, to further illustrate the correct use of virtual work in the dual code network drawing the importance of.
